At first I was planning on wiring up my bench with a few isolated outlets (via an isolation transformer). Or using a GFCI to try and protect me from toasting myself when poking around off line regulators. I kept reading, […]

The finest pitch components are the Altera FPGA and the Freescale CPU. Definitely “older” technology than a modern Tek or Agilent scope. Looks like a prototype I might build. It’s a good […]
